Reaction Steps

A microwave vial was charged with N-[(1S,2S)-2-amino-4,4-difluorocyclopentyl]-2-(2H-1,2,3-triazol-2-yl)benzamide (Intermediate 46; 50 mg, 0.15 mmol), 2,3-difluoro-5-(trifluoromethyl)pyridine (CAS number 89402-42-6; 29 mg, 0.16 mmol) and DIPEA (26 μl, 0.15 mmol) in dry DMSO (485 μl). The reaction mixture was subjected to microwave irradiation at 120° C. for 30 minutes then partitioned between ethyl acetate and water. The organics were washed with water and brine, dried over sodium sulfate, filtered and concentrated in vacuo. The crude material was purified by column chromatography (silica, 0-60% ethyl acetate/petrol) to afford the title compound.
